Just re-reading your post I thought I would add the following thoughts.
If 25 watts from a particular antenna is
full quieting and 15 watts from the same antenna
sequentially measured...is noop... this is not a
duplexer problem... those 2 numbers are less than
2 db apart you
As an LMR tech who has seen more than a few
duplexers screwed up by seemingly competent people I need to weigh in here
I would never recommend seat of the
pats duplexer tuning on site as a superior
solution to a lab alignment but the variables
need to be removed..That does not
TX/RX will be very close to that as it is the nature of
ganging 2 pass /reject cans on each side of a duplexer... 2 cans on
each side actually widens things out as compared to one, but 2 are
deeper passes and reject notches than one three cans gets
wider/deeper yet... 4 cans
Pre OS boot machine BIOS on most modern P3 class or newer laptops can
see a usb drive device such as a floppy, cdrom or in P4 and later
cases now flash drives. For the most part anything P3 800 or older
will not see a flash drive without a software driver sub system...
however in many cases P3
A simple solution to your dilemma is to pull the drive and connect it
with a $12.00 adapter to a modern 3.5 ide drive bay desktop computer,
format the drive as fat32,copy the win98se directory off of the cdrom
to the 2.5 laptop drive.. stick the laptop drive back into the
laptop.. boot from a
CF-27's are probably as easy or easier to find and maybe
cheaper on Ebay... We have been using them for DOS radio RSS
programming for a long time... and generally the batteries cost more
than the laptop...many are 300/350 mhz processors, some 500-550
mhz... I have one (PIII 500) set
